- 运动生理学 运动生理学
背景情况:
- EnodePro®通常用于阻力训练中跟踪棒速度,以建立负载速度配置文件.
- 对于EnodePro®在估计最大强度时的可靠性和有效性存在担忧,由于速度被高估,这可能会给健康带来风险.
研究的目的:
- 调查测量不精确性是否解释了与EnodePro®设备相关的测量误差差异.
- 将EnodePro®的速度测量与高分辨率位移传感器进行比较.
主要方法:
- 来自EnodePro®的速度测量与高分辨率的移位传感器进行了对比,用于腰和长椅压力练习.
- 参与者 (n=53) 进行了30%,50%和70%的一次重复最大 (1RM) 的提升.
- 分析了类内相关系数 (ICC),系统偏差和平均绝对误差 (MAE).
主要成果:
- 速度测量显示了运动的特异性, (0.204-0.991) 和长椅压力 (0.678-0.991) 的 ICC 值各不相同.
- EnodePro®始终报告了更高的速度 (p < 0.001-0.176) 的平均绝对误差 (MAE) 为0.036-0.198 m/s (4.09-42.15% MAPE).
结论:
- EnodePro®似乎高估了条形速度,可能导致一次重复最大值 (1RM) 的估计不准确.
- 该研究强调了EnodePro®用于力/负载-速度分析的有效性问题.

Non-destructive Tests for Concrete Strength
Dynamic Modulus of Elasticity of Concrete
The sonic test is a common method to determine the dynamic modulus. In this test, a concrete beam, sized either 6 x 6 x 30 inches or 4 x 4 x 20 inches, is clamped at its center. Vibrations are initiated at one end of the beam by an electromagnetic exciter unit powered by...

Assessment of blood pressure in brachial artery(one-step method)

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
